Problems solved by technology

Existing bucket teeth are wedge-shaped, flat, sharp-knife, etc. Wedge-shaped and flat-shaped bucket teeth become blunter as they are used. The sharp-knife type is sharper but has low strength and low wear resistance.

Embodiment Construction

[0015] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a method for preparing bucket teeth for excavation, including a connecting seat 1 and a tooth tip 2, the left and right side walls of the connecting seat 1 away from the tooth tip 2 are provided with counterbore holes 3, and the tooth tip 2 Concave surfaces 4 are provided on both sides of the upper and lower end surfaces. The concave surfaces 4 extend from the connection between the connecting base 1 and the tooth tip 2 to the front edge of the tooth tip 2. The middle of the two concave surfaces 4 is inclined downward. The reinforcement part, the free end of the tooth tip 2 is provided with tines 7 separated at equal intervals, and a first rib 8 and a second rib 81 are arranged between adjacent tines 7, the said The first ribs 8 and the second ribs 81 are alternately arranged.

Abstract

The invention provides a manufacturing method of bucket teeth for excavating. The bucket teeth comprise a connecting base and tooth tips. The left side wall and the right side wall, away from one endsof the tooth tips, of the connecting base are provided with counter bores. The two sides of the upper end face and the lower end face of each tooth tip are provided with concave surfaces. The concavesurfaces extend to the front edges of the tooth tips from the connecting portions of the connecting base and the tooth tips. The reinforcing portion inclining downwards is arranged between every twoconcave surfaces. The free end portions of the tooth tips are provided with sharp teeth separated at equal intervals. A first reinforcing rib and a second reinforcing rib are arranged between every two adjacent sharp teeth. The first reinforcing ribs and the second reinforcing ribs are arranged in a staggered manner. The free end portions of the tooth tips are provided with the separated sharp teeth, the keenness degree of the tooth tips is improved, excavation is benefitted, the sharp teeth are provided with the first reinforcing ribs and the second reinforcing ribs in a penetrating manner, the first reinforcing ribs and the second reinforcing ribs are arranged in a staggered manner, impact force borne by the sharp teeth is dispersed, it is ensured that the sharp teeth cannot be bent or deformed under the larger impact force, and the service life of the bucket teeth can be effectively ensured.

Description

technical field [0001] The invention relates to the field of excavator accessories, in particular to a method for preparing bucket teeth for excavation. Background technique [0002] Bucket teeth are consumable parts in the working process of the excavator, especially the tooth tip, when it contacts with the contact material at high speed, the impact force is relatively strong. If the strength is relatively low, the tooth tip is prone to deformation. With the increase of the excavation depth The relative movement with the material will produce a positive extrusion force on the entire surface of the bucket teeth, especially when excavating rocky materials, the friction between the bucket teeth and the material is greater, so the strength and structure of the bucket teeth determine the The service life of the tooth; on the other hand, the sharpness of the tooth tip determines the working efficiency. If the tooth tip is too thick and dull, the digging resistance will be large, ...
